Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology
Your Input:
mtrBSensor histidine kinase MtrB; Member of the two-component regulatory system MtrA/MtrB. Probably functions as a membrane-associated protein kinase that phosphorylates MtrA in response to environmental signals (By similarity). MtrB may be active only at septa where it promotes MtrA phosphorylation and MtrA regulon expression, probably playing a role in cell division. (528 aa)
lpqBLpqB protein; May modulate activity of the MtrAB system in controlling homeostasis of the cell wall and cell division. Belongs to the LpqB lipoprotein family. (585 aa)
fbpBAntigen 85-C; The antigen 85 proteins (FbpA, FbpB, FbpC) are responsible for the high affinity of mycobacteria for fibronectin, a large adhesive glycoprotein. They also help to maintain the integrity of the cell wall by catalyzing the transfer of mycolic acids to cell wall arabinogalactan and through the synthesis of alpha,alpha-trehalose dimycolate (TDM, cord factor). They catalyze the transfer of a mycoloyl residue from one molecule of alpha,alpha-trehalose monomycolate (TMM) to another TMM, leading to the formation of TDM (By similarity). (325 aa)
ripASecreted cell wall-associated hydrolase; Peptidoglycan endopeptidase that cleaves the bond between D- glutamate and meso-diaminopimelate. Binds and degrades high-molecular weight peptidoglycan. Required for normal separation of daughter cells after cell division and for cell wall integrity (By similarity). (497 aa)
katGCatalase/peroxidase HPI; Bifunctional enzyme with both catalase and broad-spectrum peroxidase activity. May play a role in the intracellular survival of mycobacteria. (748 aa)
katG-2Catalase/peroxidase HPI; Bifunctional enzyme with both catalase and broad-spectrum peroxidase activity; Belongs to the peroxidase family. Peroxidase/catalase subfamily. (688 aa)
wag31DivIVA protein; Important for maintaining cell shape and cell wall integrity by localizing peptidoglycan synthesis to the cell poles. Protects PbpB (PBP3, FtsI) from oxidative stress-induced cleavage. Belongs to the DivIVA family. (272 aa)
sepFConserved hypothetical protein; Cell division protein that is part of the divisome complex and is recruited early to the Z-ring. Probably stimulates Z-ring formation, perhaps through the cross-linking of FtsZ protofilaments. Its function overlaps with FtsA. (214 aa)
ftsZCell division protein FtsZ; Essential cell division protein that forms a contractile ring structure (Z ring) at the future cell division site. The regulation of the ring assembly controls the timing and the location of cell division. One of the functions of the FtsZ ring is to recruit other cell division proteins to the septum to produce a new cell wall between the dividing cells. Binds GTP and shows GTPase activity. (385 aa)
ftsQPutative Cell division protein FtsQ; Essential cell division protein; Belongs to the FtsQ/DivIB family. FtsQ subfamily. (333 aa)
pbpBPenicillin binding protein transpeptidase domain protein; Identified by match to protein family HMM PF00905; match to protein family HMM PF03717; Belongs to the transpeptidase family. (648 aa)
rpfBResuscitation-promoting factor RpfB; Factor that stimulates resuscitation of dormant cells. Has peptidoglycan (PG) hydrolytic activity. Active in the pM concentration range. Has little to no effect on actively-growing cells. PG fragments could either directly activate the resuscitation pathway of dormant bacteria or serve as a substrate for endogenous Rpf, resulting in low molecular weight products with resuscitation activity (By similarity). Belongs to the transglycosylase family. Rpf subfamily. (375 aa)
mprADNA-binding response regulator; Member of the two-component regulatory system MprB/MprA which contributes to maintaining a balance among several systems involved in stress resistance and is required for establishment and maintenance of persistent infection in the host. Functions as a transcriptional regulator that recognizes a 19-bp nucleotide motif comprizing two loosely conserved 8-bp direct DNA-binding motif repeats separated by a 3-bp spacer region (By similarity). (230 aa)
sucCsuccinyl-CoA synthetase, beta subunit; Succinyl-CoA synthetase functions in the citric acid cycle (TCA), coupling the hydrolysis of succinyl-CoA to the synthesis of either ATP or GTP and thus represents the only step of substrate-level phosphorylation in the TCA. The beta subunit provides nucleotide specificity of the enzyme and binds the substrate succinate, while the binding sites for coenzyme A and phosphate are found in the alpha subunit. (387 aa)
ABK70824.1Hypothetical protein; Identified by Glimmer2; putative. (136 aa)
katG-3Catalase/peroxidase HPI; Bifunctional enzyme with both catalase and broad-spectrum peroxidase activity. May play a role in the intracellular survival of mycobacteria. (739 aa)
dnaAChromosomal replication initiator protein DnaA; Plays an important role in the initiation and regulation of chromosomal replication. Binds to the origin of replication; it binds specifically double-stranded DNA at a 9 bp consensus (dnaA box): 5'- TTATC[CA]A[CA]A-3'. DnaA binds to ATP and to acidic phospholipids (By similarity). (504 aa)
mtrADNA-binding response regulator MtrA; Member of the two-component regulatory system MtrA/MtrB, responding to environmental signals (Probable). Controls expression of a number of genes including dnaA, ripA, fbpB and probably itself. Probably plays a role in cell division. (228 aa)
whiB3Transcription factor WhiB; A redox-sensitive transcriptional regulator. Maintains intracellular redox homeostasis by regulating catabolic metabolism and polyketide biosynthesis. Regulates expression of the redox buffer ergothioneine (ERG). In concert with myothiol (MSH), another redox buffer, responds to low pH leading to acid resistance. The apo- but not holo-form probably binds DNA (By similarity). (96 aa)
rpoBDNA-directed RNA polymerase, beta subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. This subunit often mutates to generate rifampicin (Rif) resistance. Interaction with RbpA partially restores Rif-inhibited transcription; once the subunit is Rif-resistant however RbpA no longer stimulates transcription. (1169 aa)
dnaNDNA polymerase III, beta subunit; Confers DNA tethering and processivity to DNA polymerases and other proteins. Acts as a clamp, forming a ring around DNA (a reaction catalyzed by the clamp-loading complex) which diffuses in an ATP- independent manner freely and bidirectionally along dsDNA. Initially characterized for its ability to contact the catalytic subunit of DNA polymerase III (Pol III), a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria; Pol III exhibits 3'-5' exonuclease proofreading activity. The beta chain is required for initiation of [...] (397 aa)
